Glock pistols do not feature conventional manual safety levers,
however they are equipped with a revolutionary, fully automatic safety
system consisting of three passive, independent, mechanical safety
devices that collectively form the Glock Safe Action safety system.

GLOCK SAFE ACTION SAFETY SYSTEM

Glock Trigger Safety - this is incorporated into
the center of trigger itself in the form of a lever. In the forward
position the lever blocks rearward movement of the trigger. To fire
the pistol, this little lever must be deliberately pressed at the
same time as the trigger. If it's is not depressed, the trigger will
not move rearward and the pistol will not fire. This is designed to
prevent unintentional firing when the pistol is dropped, falls or is
subjected to the forces such as inertia or external pressures.

Glock Firing Pin Safety - this projects into the
firing pin channel and mechanically blocks the firing pin from
moving forward. When the trigger is being moved rearwards, a
vertical extension of the trigger bar pushes the firing pin safety
upwards, clearing the firing pin channel. During the slide cycling
process, the firing pin button safety automatically engages with an
assist from the firing safety spring. This safety was designed to
avoid unintentional firing in the event that extreme forces cause a
separation of the slide and receiver.

Glock Drop Safety - The rear part of the trigger
bar, which has a cruciform shape, rests with both arms on the drop
safety shelf located in the trigger mechanism housing. When the
trigger is pulled to the rear, the trigger bar begins to move off
the safety shelf as the trigger bar is forced downwards and
rearwards by the connector until finally separating from the firing
pin lug. During the slide cycling process, the connector is pushed
inward by a cam in the slide releasing the trigger bar which is then
lifted with help from the trigger spring and caught by the firing
pin lug. The trigger bar is engaged by the firing pin lug and both
arms are pushed onto the drop safety shelf again.
